| Abstract: | Curved carbon nanotubes were prepared by pyrolysis of acetylene in the presence of cobalt catalyst. Through deeply researching into the influence of the technique parameters on the yield and the microstructure of these carbon nanotubes, we got a better technique curse. The microstructure of carbon nanotubes was investigated by transmission electron microscopy, high resolution transmission electron microscopy and Raman Spectroscopy. The formation mechanism of curved carbon nanotubes was also discussed. |
